The determination of obesity that develops with an increase in the percentage of fat in the body may not always be possible in the real sense with body mass index, which is frequently used in practice. This study aimed to compare the results obtained from body mass index and bioelectrical impedance analysis measurements in evaluating obesity in Turkish school-aged children using age-related percentile curves.
The study included 1127 children (604 boys and 523 girls) recruited from a screening of the schools in the city center of Isparta between May 20 and June 20, 2014. Body mass index was calculated, and the variables of fat mass, body fat percentage, fat-free body mass, and total body water were measured with a Tanita BC-418 MA device.
According to the body mass index values, 23.8% of the study sample was overweight/ obese, and according to bioelectrical impedance analysis, this rate was 14.7%. When examined by gender, males' overweight/obese ratio was 19.9% (overweight 11.3% and obese 8.6%) according to body mass index and 12.9% (overweight 7.1% and obese 5.8%) using the bioelectrical impedance analysis method. In females, the overweight/obese ratio was 19% (overweight 9.4%, obese 9.6%) according to body mass index and 16.7% (overweight 9.6% and obese 7.1%) using the bioelectrical impedance analysis method.
The results obtained from the weight-based body mass index method were not consistent with the body fat percentage results obtained with the bioelectrical impedance analysis method. Since the fat ratio is also crucial in evaluating obesity, care should be taken when diagnosing obesity using body mass index only.
在实际应用中，常用的体重指数可能并不总能真正确定因体内脂肪百分比增加而导致的肥胖。本研究旨在使用与年龄相关的百分位数曲线，比较体重指数和生物电阻抗分析测量结果在评估土耳其学龄儿童肥胖方面的差异。
该研究纳入了2014年5月20日至6月20日期间从伊斯帕尔塔市中心学校筛查中招募的1127名儿童（604名男孩和523名女孩）。计算体重指数，并使用Tanita BC - 418 MA设备测量体脂质量、体脂百分比、去脂体重和总体水等变量。
根据体重指数值，研究样本中有23.8%超重/肥胖，而根据生物电阻抗分析，这一比例为14.7%。按性别分析，根据体重指数，男性超重/肥胖比例为19.9%（超重11.3%，肥胖8.6%），使用生物电阻抗分析方法时为12.9%（超重7.1%，肥胖5.8%）。在女性中，根据体重指数，超重/肥胖比例为19%（超重9.4%，肥胖9.6%），使用生物电阻抗分析方法时为16.7%（超重9.6%，肥胖7.1%）。
基于体重的体重指数法所得结果与生物电阻抗分析法测得的体脂百分比结果不一致。由于脂肪比例在评估肥胖中也很关键，仅使用体重指数诊断肥胖时应谨慎。
